had a DR call me that 1 time because I wanted to be put to sleep instead of him just giving me 4 locals and start cutting he smarted off after the surgery and said now that was not that bad was it I simple said that is the last time you will cut on me and did not use him after that next time used another DR from his office but agreed with me about being put to sleep said it made it a lot easier for the patient and him also .
